A lot of the movie was not what Shatner wrote himself and intended it to be. Paramount hired another writer to put in all those so called jokes and funnies that turned out to be quite rediculous. Shatner's version did not have McCoy doing all that drinking and cussing and no implied relationship between Scotty and Uhura. Jay from Bring Back Kirk was working on redoing the special effects and film, putting it back to the way Shatner originally wrote it but I don't know what became of the project.
Do you know where there's a link to the original Shatner version? I'd love to give it a read.

Thanks, wjaspers. I think my take on the movie is similar to Myasishchev's; I liked the Sybok we got and the film only needed three things: better special effects, a more dramatic ending, and a little less humor painting the crew as idiots.
